Opinions and observations from environmental experts, activists, and luminaries

The small farmers of southern Chile teach another valuable lesson about sustainable agriculture: they cultivate dozens, perhaps hundreds, of locally adapted varieties. On the island of Chiloe, west of Pumalin Park, farmers grow dozens of kinds of potatoes. In the farmers' markets on Chiloe, I found blue potatoes, two-toned potatoes, and many others, all with distinctive flavors and textures--and probably with distinctive disease and pest resistances, soil adaptations, and so forth. Just north of Pumalin Park, I visited a woman who grew many kinds of medicinal herbs in her small garden, including some that our native Chilean guide had not known about before. The larger, agribusiness-style farms of northern Chile don't grow these varieties. That means the small farmers of Patagonia's mountain valleys and foothills play an especially valuable role in keeping a diversity of crop varieties alive, a genetic heritage we'll need as climate changes, plant diseases and insect pests adapt, and nature evolves.
